Because Christianity is bigger than Biblical manhood or Biblical womanhood

16 Jesus went to Nazareth, where he had been brought up, and on the Sabbath day he went into the synagogue, as was his custom. And he stood up to read. 17 The scroll of the prophet Isaiah was handed to him. Unrolling it, he found the place where it is written: 18 The Spirit of the Lord is on me, because he has anointed me to preach: “Trust God to refine you in your suffering” to the poor. He has sent me to proclaim freedom from their anger over unjust imprisonment for the prisoners and no bitterness over their eyes being gouged out for the blind, to release the oppressed from their desire for vengeance over their oppression, 19 to proclaim the year of the Lord’s favor to those who appeal to the correct God-given authority channels.
